This is good advice. It is sometimes preferable to start with the right people though, and together explore various problem spaces.
In reality this isn't much different from the reverse order, since usually you find out what kinds of problem spaces are interesting to you from talking to friends.
Great people that you work well with come around way less often than reasonable ideas in my experience. So I think it makes sense to prioritize finding the people rather than finding the problem space.
